callyl and to shift the cushion in order to pre-I sent theseveralsurfaces to the brushing device. It has been suggested in theprior art that these cushions be mounted on a lbelt or similartravelling platform and passed beneath or `between brushes mounted toro- 30 tate about fixed or` substantially` finedV axes of rotation..From a practical standpoint howeverthis method of feedingthe cushions tosuch brushes has not proven satisfactory M due among other reasonsto'the fact that w as the cushions arenot uniform 1n size, and certainparts'of the surface under treatment require a more vigorous applicationof the brushing treatment than the other parts, the necessary variationin treatment cannot be o attained where all parts of the surfaces aresubjected to the same'brushing treatment.

Accordingly, one of the objects of the in# ventionvis to provide asimple form of machine by means of which the intensity of vbrushingengagement between thebrush and the surface under treatment may be atall times under the sensitivemanual controloff an operator who canadjust the pressure of the brush on the surface as the circumstancesrequire andV repeat the operation over the same surface as long asnecessary.

Car cushions Vof the type now in general use are quite heavy, weighingfrom forty to fifty pounds when wet; theyk are somewhat bulky and do notprovide any means for gripping them conveniently and they are otherwisenot easily handled.

Accordingly, another object of the inventionis to provide asimplied formof mech- 59 anism for handling the heavy cushions and for turning theVsame quickly andv accurately into positionrto" permitan economicsequence of brushing operations and at thesametime to provide such amachine designed so-thfatI boththebr'ushing operation and themanipulation of the cushions` can be attained bythe employmentofone manfor each machine:

Still another object ofl the invention'- is to provide asimpliiied'form3 of' machine of the' type outlined-which can. beInadesutliciently' rugged in itsseveral parts to withstand the roughusage towhich such'a machine' islsub# jected and at the sameit-im'e tolprovide'a ma'- chine. which Y canzbeV constructed of .relatively fewparts 1 without extensivermachining fop-- eration so that. itcan Ybemanufacturedvand marketed at relativelyf low acost.

Still another object :ofjvthe invention isto provide amachinefoftheftype foutiinedin which the' necessary power to operate it,eX- cept the `power necessary tn drive the revolving and travellingbrush,'will1be manualpow# er ofthe operator:attendingithe machine.

InV the following description and in the claims, parts will beidentified by specific names for convenience of expression but they areintended to be as generic in their application to similar parts as theart will permit.

The foundation of the machine comprises a rectangular box-like structureincluding four corner uprights 15 connected adjacent their upper lendsby means of front and rear end sills 16 and relatively deep side sills17 in the form of channel members. Extending across thev top of theskeleton frame thus formed is a top plate 18, and it is understood thatthis frame is otherwise reinforced and braced to form a rugged structureby structural parts some of which will be specifically mentioned inconnection with other mechanism. Gn top of the frame and adjacent itscentral forward edge is a turn table 19 for supporting the cushion Cflatwise as shown in Fig. 2. Positioned in advance of the front edge ofthe supporting frame is a vertically movable cushion elevating carriage20 for supporting the cushion edgewise and in vertically disposedposition as shown in Fig. 3. In advance of the cushion in all positionsthereof is a brush 21 mounted for rotary movement about its ownvertically extending axis and driven through a flexible cable 22 leadingfrom a motor or other suitable source of power.v The brush is movedbodily back and forth across thel front of the machine by a gear drivenbrush rotating and shifting mechanism contained in the reciprocatinggear box 28 acting on rack 24 and which brush actuating mechanism ispartially shown in this application andis more fully disclosed in mycopending application entitled Brush mechanism lfor cushion brushingmachine, Serial No. 133,309 filed under even date.

The brush 21 is mounted in a horizontally movable brush carriage 25slidably mounted so as to bring the brush in variable brushingengagement with the 'cushion in its several adjusted positions. Thebrush carriage includes a front frame 26 extending across the front ofthe machine and formed largely of the brush actuating mechanismk andframe for lcarrying the same. From opposite ends ofthe front frameextend side frames 27 which project therefrom each along the adjacentside ofthe side sills 17. The side frames each include a righttriangular shaped forward part 28 as shown in Fig. 2 and a rearwardlyextending horizontal arm 29 of inverted T shape in horizontal crosssection as shown in Fig. 5. Y

It is the intent of the designer of this structure that, insofar as ispossible, the weight of the brush carriage 25 be carried ou the forwarduprights 15 and inv this way minimize the strain which otherwise wouldhave to be transmitted through the side sills and other parts of thesupporting frame. For this purpose the carriage is supported largely bydisposing the two side frames 27 thcz'cof on flanged rollers 30 which inturn are carried by the uprights 15 as particularly shown in plan inFig. 1 and in side elevation in Figs. 2 and Ll. Spaced inwardlytherefrom in each case are a pair of roller guides 31 and 32 rotatablymounted on the side sills 17 and which rollers engage respectively theupper and lower side of the bottom flange 33 forming the head of the Tarm 29 as shown in Fig. 5. lt is obvious of course that these rollersassume some of the weight of the carriage 25 as this weight becomesunbalanced on opposite llO sides of the rollers 30. The carriage ismoved from front to rear and into engagement Awith the cushion b y meansofV a ttor fardly inclined` as a control for the turntable and a controlfor a gripping device 35, depending upon the po y sition of thecarriageall as will be more fully disclosed hereinafter.

`The turn table 19 is an oblong plate provided on the upper sine thereofwith a` pair ofupwaruly facing channel bars 36 disposed` in parallelrelationand spaced equidistant on opposite sides of the airis ofrotation of the turn table. The cushions @usually have a central bulgeor dept-h adjacent the center greater than at the edge as'clearly seenin Fig. 2 and these channel bars assist in insuring the retention of thecushion on the turn table as is rotated.` The turn table is designed toturny With a step by step motion so as to presen'tthe four side Vedgesof thecushion to the plane of movementof the brush as it is reciprocatedback and forth across the front frame 26. It

ieobviously essential not only to rotate theV turn table ninety degreesat eachstep but it is alsonecessary` to holdV the turn table fromrotating thereby to hold the cushion rigidly in place as the brushtravels back and forth across the surface of the cushion exposed to thesame. For this purpose the turn table is controlled by zin-intermittentfeed `movement arranged to rotate the turn table a step at a time untilall four sides of the cushion have been `presen-ted to thebrushingopera# tion hereinafter 'described his `noted par?Y ticula 'ly in Figs.6 and 7 the turn table andr the driving parts turning therewith are as'-sembled as a complete unit, and mounted on abase plate 37 and which inturn is supported on the lower flanges 38 of a pairrof channel shapesills 39 and 40 extending from table is demountablyf secured byscrevvslt.V`

Depending from the lower flange '-of the locking Wheel and positionedexteriorally of the hub l2 are four equally andvcircumferentially spacedapart rollers 48 constituting locking pins and between these locking Sfpins Vand adjacent the outer edge of the flange @i7 are four advancingpins 49. rIhese pins are disposed so as to beV engaged by a pawl 50 toadvancethe locking Wheel, and with it the turn table and cushion C intoits succeeding positions to present all four side edgesofythe` cushionto the lorush` 21.A AThe.

pawl iscarriedby a slotted .bar'l slidably mounted for rreciprocatory,movement inl Vguidevvays 52 provided therefor. These guidewaysjarevformed in the top face of blocks 53 four of'Which are shown in Fig. V6,

secured to the base` plate 37:1 Theloar 51 is" demountably secured `insaid guideways by Vplates 54C secured to. the top of the blocks byscrews 55.- The'bar 51 is reciprocated from fronttoi rear of themachineby mechanism actuated from the lever 34 as hereinafter described. ThepaWl 50 is maintained normally'in thevpath of rotary'movement of theadvancingpinsll) by means of a pawl spring 56 Which tends normally tomove` the paWl into engagement ywith a paWl stop 57. The

patvl is of the Oneway/acting type arranged to advance or ratherto-start the rotary action of the turn table locking Wheel clockwise asindicated by the arrow 1in Fig. l and the pawlr is arranged so thatonthe retreatof the slotted bar 5l itis free tovpass the next advancingpin49 Which has been rotated into position in ladvance of the pavvlduring the final period of the previous advance ofthe slotted 4bar. edgefacing the locking pins or rollers i8 with a slot or recess 58 disposedto receive and ad-l vance the lockingpin advanced into the'same by thepawl and then to act on the loclringpin to rotate the turntablevunderthe action of the intermittent feed movement illustrated. Theslotted bar is provided With a straight edge 59 constituting a lockingedgeand fromthe showing in Figs. 1 and 6 it Will be noted that thepartsare so designed that When'the4 locln The bar 5l is lprovided onthe'V ing Wheel has been fully advanced tWo of the y locking. pins i8will be in line with and one ofthem Will be held from rotation by thelocking edge and Will be so held until the next advance of the slottedbarvpermitsand causes the foremost of these tivo lool-:ing pins 48'tomove intoV and` out of the slots 58.

The slotted bar'l is reciprocated baclrand forth to rotate the turntablethus dese V1ibed and -to release the gripping device 35 through theroclring of the main shaft 605'actuated by control lever 3e andcontrolled by the position of the carriage side frames 27.

rllhe main shaft 'extends longitudinally of the machine beyond the sidesills defining right vof the machine will equally apply to thecorresponding structure at the left of the machine. The lever 61includes a foiurvardlyv extending'and depending arm 62 which isconnected by a reach rod 33 tothe lower end of an arm 64 the upper endof which arm is lill) secured rigidly to a shaft rotatably mounted inthe front frame 26. To the arm 64 at the right hand side of the machineis secured the control lever 84. lt is obvious from this constructionthat th-e swinging of the control lever can actuate the locking leversat opposite sides of the machine when a movement thereof is permitted bythe position of the brush carriage 25 and that both ends of the mainshaft are rocked simultaneously. rl"he upper rearwardly extending arm 66of the lever 61 is so disposed to be engaged by the underside of theflange 33 forming part of the arm 29 which engages the same when thebrush is close to the cushion and holds the lever 61 fromcounterclockwise rotation as shown in Fig. 2. With the carriage movedforwardly, away from the cushion and with the arm 29 clear of thelocking' lever 61 it is possible for the lever 34 to rotate and thusrock the shaft as indicated in the full and dotted line showings in Fig.4.

When in the locked position shown in Fig. 2, the reach rod 63 is heldrigidly from movement in either direction. The lever 61 cannot rotateanti-clockwise due to its engagement with the arm. 29 and the rod 63cannot move from left to right of the showing in Fig. 2 due to it beingheld by a pair of toggle links 67 which at this time is in elongationwith and in effect constitutes a continuation of the. reach rod 68securing the same pivotally connected by means of pin 68 to the adjacentrear upright 15. For the purpose of breaking the toggle connection andthus permit a rocking of the main sha-ft 60, a horizontally extendingunlocking link 69 is pivoted to the pin 68 and underlaps a pin 70 whichprojects laterally from one of the toggle links 67. To the outer end ofthis horiontal link 69 is pivoted an npstanding lifting link 71 providedwith a slot 72 containing the main shaft so as to guide the lifting linkin its vertical movement. To the upper end of the lifting link ispositioned a roller 7 3 disposed in the path of movement of a wedge 74secured to the outer end of the arm 29. From this construction it willbe noted by comparing Figs. 2 and 4 that the forward or right-to-leftmovement of the carriage will cause the wedge to engage the roller, liftthe toggle links 67 from their aligned position shown in Fig. 2 past thefull line and into the dotted line position shown in Fig. 4, so that acontinuous depression of the control lever 84 after it has advanced thecarriage to its forward position as shown in Fig. 3 will cause thereleasing of the locking toggle links and a subsequent rotationanti-clockwise of the main shaft over an angle of about forty-fivedegrees.

Tracing the link connection between the main shaft and the reciprocatingrod 51 which rotates the turn table, there is shown particularly inFigs. 3 and 9, a depending arm 75 rigidly secured to the main shaft justoutside the sill 40. The lower end of the arm is connected by a link 76to the lower end of a lever 77 rigidly secured intermediate its lengthto a secondary shaft 78 paralleling the main shaft and mounted atopposite ends in brackets 79 secured to the supporting frame as shown inFigs. 3 and 9. The upper end of the lever 77 is pivotally connected bymeans of a link 80 to the rear end of the slotted bar 51 forming part ofthe Geneva movement. From this construction it is obvious that themovement of the control lever from the full line into the dotted lineposition shown in Fig. 4 will rotate the main shaft anti-clockwise andthis motion in turn It is required however that the clamping jaws bereleased from their engagement with the cushion prior to the rotation ofthe turn table and accordingly the present disclosure features anarrangement whereby the jaws of the gripping device are moved into aninoperative position by the same mechanism which controls the turn tableand in proper timed sequence to permit the complete release of thecushion before the turn table is moved. For this purpose there isloosely mounted on the supplemental shaft 78 an upstanding arm 81 whichis normally held in inoperative position retracted towards the back ofthe machine by a spring 82. The arm is moved in the other direction andagainst the tension of the spring by means of pin 83 which projects fromthe upper arm of lever 83 fixed on shaft 78. As the lever 88 swingsunder the action of the rocking main shaft 60 it causes the arm 81 toswing with an anti-clock- 1 wise movement from right to left as shown inFigs. 3 and 9. Positioned in the path of the upper end of the arm 81 isone arm of a bell crank lever 84 (see Fig. 1) pivoted on a bracket 85extending laterally from the center sill 40 and the other arm of whichlever is designed to engage a long arm 86 the rear end of which ispivotally connected by pin 87 to the rear sill. The forward end 0f thislong arm is overlapped by and is designed to engage a stop 88 at one endof one of the movable jaws of the gripping device. A long spring 89tends to move this long arm into an inoperative position engaging a stop90 and this permits the spring 181 llO which controls thejavvs to movethesame-into clutching positionwith the cushion when released by thelonglarmduring its return into its inoperative position as shown in dotand dash lines in Fig. 1.

y It is required that the clampingjaws be positively heid- -ininoperative position as lshown invfull-flines Ein Fig.- 1`until-thelturn table has completedits quarter movement. For this purposethe arm-81 (Fig. 9) has -pivoted thereto a--loclring bar 91 provided onits underside With a flocking notch 92 and which baris designe-d toslide over a square block 93 `secured to the main shaft. The locking baris normally held `in=engageinent with a.

flatu face `ofthe block bymeans of al` spring 94 connecting the bar 91vvithfthe `arm 81. lThe main shaft is provided with a lug which? isdesigned as the main shaftl isrerotated to lift the locking bar sothatthe notch thereinW-ill Vclear the square-locking blocl and thus permitthe spring l82jto draw the-arm 81 out of position engaging the lever 84and thus permit the long arm 86 to swing bacl-z into itsv inoperativeposition undertension of its spring 89.1 Fromthis construction it isseen that-the ygripping device-.is held by the loclringbar 91ininoperative-positi'cn even after the lever V77'has begun to sWing'backand during the initial return to normallof the main shaft. Thegrippingde` viceV is held open While the lug 95 on thev main shaft isturning upwardly from the pesiti-on shown Vin Fig. 9 and until itengages the underside of and has lifted the locking ture ithere is showna long block 96 secured to the forward upper .face of which is a bracketextension'y 9T -triangular in side elevation.4 Eachof these'blocksismounted on an up right 98 and Which two uprights'are positir-med at theVfron-tof the machine spaced inwardly from the cerner uprights l and poAsiticned on opposite sides of the turn table; as shown' in Fig. 1e theseuprights 98 each comprises-two channels 99 and 100 withA their backsspaced apart. The loWerend of' the bloclr`f`90 is provided With a pairof angle pieces l101 positioned on opposite sides and engaging in thechannel of its adjacent upright asshovvn inFig. 3.y Positioned abovetheseangles is Vpair of plates 1027 103-` (see Fig. 14.) eachofvvhichcarry a pair of rollers 10a-10.5 `positioned onopposite sides of theflanges ofthe associated-channel bar. Frein this construction it isseenthat both of the blocks which ccact to form the carriage are mountedto slide freely and thisfi's particularly-necessary Wher'eheavy cushionsare tol be raised and lowered manually or by foot isslotted-asl'shown-at 110, Fig. 11, to receive a-norma'lly horizontal'extending ycushion edge suppert 111v with `its forward end upturnedasshownatf112 and'its rear end pivoted on pivotpin 113carrie'd by theupper end of the block. This supportlll-is adapted to be engaged -by atilting lever'115 pivotally mounted intermediateits length on the blockert'ension andvdesigned When the carriage is elevatedlto the limit-:ofits upwardmovement tolengage the lower edge-116 of the front sill so 'asto lift the outerfendofthe support-as indicatedin Fig. -11 andth-us 'actto tilt* the cushion from thefvertical position shown in Fig; tovfar-dsythe-turntable-or towards the cushion tilting mechanism 117 l hereinafterdescribed-When it is-des-ired tov-move Vthe cushion from thelverticalbackinto the hori- -zcntal positionne shown in Fig. 2.

The gripping device 35' for clamping the cushion is carried by thecushion elevating carriageso-as to clamp thecushion When onthefear'riagelas shownt in Fig. 3, and is also pivotally mounted so thatitfcan be lswung intovhorizontal posi-tion"when on'the turn table asshown in Fig'. 2, and-alsowhen moving from=one of theseposi-tions intothe other Vendl-ir contrclof the tilting mechanism 117.

The gripping device 35. comprises in eliect three-parallel bars (seeV10) ;-tWo outer jaws carryingbars 118 and1119-and anintermediaten-relativelyiixedbar 120. 'f rThe fixed bar Vis`:pimifct'ally-mcuntedby means vcfa pair of hingev connections 121 andinvv'ardly'projecting brackets 122 secured to theupper' inner `face ofthe blocks '96 as particularlyshovvn in Figi-13. Each of the bars 118and )1194s provided 'adjacent its outer endfwith y.'lsli'a'pedelevatingmember 123. Thefouter endofthe-bar 119 is `provided With theIupturned stopjl vpreviously referred to. These elevating members 123each include a laterally-1 extending-'i' member '124 `provided with twoupstandingfcushion engaging pins 125 constituting 'the vclamping jaws.These elevating members also include a laterally extending member 125having a length sufficient to extend under the cushion, and of a lengthsufcient to overlap the tilting mechanism 117. The forward ends of eachof the members 124 are formed into a rectangular block 127 whichencircles the ba'rs`118, 119 and 120. The left block is secured to thebar 118 and the right block is secured to the bar 119 by means of screws128. Adjacent faces of the bars 118 and 119 are provided with racks 129in mesh with a pinion 130 carried by the fixed bar 120 and so arrangedthat movement of one ofV the bars is transmitted therethrough to theother. A spring 131 between the blocks 127 tends to cause these crossmembers to be moved normally into cushion clamping position whenreleased by the long arm 86.

Mounted in the front of the machine adj acent the ground is a shaft 132journalled in brackets 133 carried by forwardly projecting extensions134 from the base of the machine. Secured to the shaft adjacent theright side of the machine is a lifting arm 135 connected by a link 136to the lifting lever 107 which controls the raising and lowering of thevertical carriage 20. As it is intended that the carriage be moved witha step by step movement to permit the brush to traverse across the faceof the cushion along succeeding bands as the cushion is elevated ordepressed step by step, a disk 137 provided with a series of one-waynotches 138 is secured to the body of the machine by a bracket 139.Loosely mounted on the shaft adjacent the disk 137 is a foot pedal 140provided with a pawl 141 adapted to engage in the notches on the disk.rlhe pedal 140 is provided with a pin 142 which engages a shoulder 143on the arm 135 to elevate the same. The pawl is controlled by a toeplate 144 pivoted to the outer end ofthe pedal and designed to be rockedto remove the pawl from the notches when it is desired to permit thecarriage to drop which it will do of its own weight.`

The tilting device 117 includes a pair of tilting arms 145 hingedlymounted on the front sills on a bracket 146.V The arms 145 arepositioned to the outside ofthe cushion in all positions of the same andin each case underlap the transversely extending members 124 of theclamping device so that when the tilting member is elevated it willcarry with it the means for holding the cushion from lateral movementparallel to the width of the machine. Each tilting arm is controlled bya pair of pivotally connected lifting links 147 148 the latter of whichis connected'by means of a reach rod 149 to a tilting arm 150 looselymounted upon the shaft 132. s

This lever is controlled by a foot pedal 151 fixed to the shaft 132 andprovided with a pawl 152 designed to engage the single notch 153 in anotch plate 154 secured to the extension 134. A lug 155 on the pedal 151acts on a projection 156 on the arm 150 tol raise the same and with itthe arm 148 of the tilting device. The shaft 132 provides the connectingmeans between the two arms 150 as particularly shown in Fig. 1.

From this construction kit is understood that depressing the foot pedal151 acts throughv the two linkages to lift the tilting device asa unitfrom the horizontally disposed position shown in Fig. 2 into thevertically disposed position shown in Fig. 3 at the end of whichmovement the pawl 152 engages in the notch 153 to hold the tiltingdevice in the upright position shown in Fig. 3. Releasing the pawl 157by the depression of the toe releases the locking effect and permits thetilting device to fall back by virtue of its own weight into its normalhorizontally disposed position on opposite sides of the turn table asshown in Figs. 1 and 2.

rlhe lug and projection form of connection shown at 142, 143 permits thepedals to be lifted up out of the way when not in use and disposedvbeneath the horizontal carriage 25 as shown in dotted lines in Fig. v2.

In operation the cushions, after they have been dipped into or sprayedwith some suitable cleansing material usually employed in this art, arepositioned on the turn table as shown in Fig. 2 and while the brush isin spaced relation to the adjacent edge of the cushion as indicated inthe position of the brush shown in Fig. 3. Vhile positioning the cushionon the turn table the gripping device is moved into its inoperativeposition, spaced from the cushion as indicated in Fig. 1. No particularcare need be exercised in positioning the cushion on the turn tableexcept to make sure that the bulged center of the cushion is positionedbetween the parallel channel members on the top of the turn table.Releasing the gripping device permitsv it to engage opposite side edgesof the cushion and tends to center and to hold the same against theshift-ing effect of the brush. The brush is caused to rotate; thespraying device 159 is set in operation and the brush is caused whilerotating to reciprocate back and forth across the front of the machineas is more particularly defined in the above identified co-pendingapplication. Y

Bylifting the hand lever at the right of the machine the operator causesthe brush as a whole to be moved from front to rear and into operativebrushing engagement with the side edge of the cushion which is facingthe same as indicated in Fig. 2. By means of this lever the operator maymaintain any desired intensity of brush engagement with the cushion.

TWhen one side edge is brushed the operator depresses the control leverto withdraw the brush from the cushion and at the end of the outwardmovement of the brush carriage the gripping device is released ashereinbem notches 138 one at a time.

mer/cried fore described. On the upstroke the turn table is rotated bythe action of thefGreneva movement so as to bring the neXt adjacent sideedge into the planeiof movement ofthe reciprocating brush and the clampsarereleased as the turn table completes 90 revolutions and about thetime the control lever 341-. is horizontal. The operator then continueslo lift the control handle from the horizontal position towards theelevated position shown in Fig. 2 to bring the brush into engagementvrith this brush surface.` This Loperation is repeated until all fourside edges of the cushion have been brushed.

.By pressing the proper lever for controlling the tilting mechanism thecushion and with. it the gripping device is elevated from the horizontalposition shown in Figs. 1 and 2 into an elevated position somewhatraised from the `position shown in Fig. 3 at which time the liftingcarriage is in its uppermost position and disposed to receive thecushionas. it is dropped on to the same. When elevated asshown in Fig; 3 theclamping device is resting on top of the bracket 97 and the members 145are held elevated to prevent the pressure of the brush from tilting thecushion back on tothe turntable. A hook 158 projecting from the free endof each of the members 1115 is disposed When elevated to receive the arm126 .and act thereon to return the clamping device to the horizontalposition shown in Fig. 1 and Fig. 11. YVith the cushion thus held in its.vertically disposed position'the brush is. advanced into engagementWith the wide surface ofthe cushion and the operation is repeated as hasbeen described for the brushing ofthe side edges.

Preferably the brush is of less heighth than the corresponding dimensionof the flat side of the cushion and in this case the brush caused totraverse horizontal bands of brushedspacesV across the face of thecushion. Preferably the brushing operation is started at the bottom ofthe cushion With the carriage 20 in its highest position somewhat abovethe position shown in full lines in Fig. 3 and in Which position it isheld by the pedal 14() engaging one of the end notches in the notchplate at thebase of the machine. As each band is successively brushedthe carriage is lowered a distance to bring apartiallybrushed orunbrushed portion of the cushion into position facing the brush untilfinally the elevating carriage is in its lowermost position shown indash lines in Fig. 3.

This gradual. lowering of the carriage is attainedsiniply by depressingthe lever l140l so that its pawl 141 Will engage succeeding Thissuccessive `brushing of succeedingly spaced bands is continued until theentire flat `surface; or vtopof thecushion hasA been treated.

After being brushed, theV rinsing spray 159 is turned on. andthecushionis then brushed the-combination; ofwmeans including a band after bandpreviously described eX- cept that `the cushion iselevatedfstepfby. step`untill the 'lifting carriage is-moved to the limit of itsupwardfmovement.
